Be it known that we, PAUL F. v. M HRER= and JOHN PHILIP Horr, subjects of the Em` peror of Germany, and JO'HNH'OPP, a citizen of the United States, residing inthe city of Philadelphia, State of Pennsylvania, have invented certain new and usefullmprove-v ments in Acetylene-Gas Apparatuspof which the following isa specication.

ings, and then pointedoutlin the claims.

In the drawings, Figure yl is a'verticals'ectional View, partlyvineleva'tion, of'our improved acetylene-gas apparatus. Fig. 2 isa vertical sectional'view vvof ,the carbid-holder."

Fig. 3 is a plan of thesame. Fig; 4 is a detail in elevation, illustrating means whereby' an alarm is sounded electrically whenl the quantity of gas in the gasometer is reduced beyond a serviceable limit.

Referringv to the drawings,- l represents the generator, comprising a liquid-holding receptacle divided into two chambers-a charging-chamber 2 and agenerating-charnber 3- by a vertical partition 4,-asshown.: The outer wall 5 of the generator and also the upperend of the partition extend above the top of the generator, forming a tank to receive water to serve as a seal. The lower end of the parl' tition extends to near the bottom ofthe generator, leaving a space sufficient to permit the carbid-holder to be passed beneath the partition, as hereinafter described. A pipe 7, leadin'gfroln the generator, servesto convey the gas into a cleanser t5, comprising a vessel havinga suitable water-inlet 9, through which water is poured ntothe cleanser until its level is above th'efexit end of pipe 7 whereby all gas is caused to pass through the water in the cleanser before delivery to the gasometcr. A tap 10 serves to permit draining of the clea engaging a suitable keeper 28. l *n '29'is connected to the bolt and tolagstud 30, r fixed in the top of the holder, anda second through said inlet. A pipe l2,v leading from the cleanser, conveys thegas Lto a bell 13 of thegasometer,` whicli rises andlf'allsin the usual water-containin g vessel14,being guided in operation by rollers l5', the upperones'rofV which bear againstthe rods of frame 16, while the lower Ones bear against the'in'ner wallof nser when desired, a'.stop-cool:` 11- '.in Vthe `water-inlet 9 lprewe'n'ting escapeof gas vessel 14. The` top of 4bell`1f3is `preferably cone-'shaped and is centrally provided with a relief-'valve 17. The outer wall of the bell 13 projects beyond the cone'fshaped top 18 to provide a tank 19 to receivewatefr to'form a seal against leakage and" at the'sam'e time provide a convenient wayof counterweight-L ing the bell. `A'suitable exit-pipe 20 c gas from the gasometer for use. p

` The carbid-'holder 21 comprisesiametal receptacle having a hi'nged'top- ,22,- which is adapted to snugly fit the holder, being pref` erably provided Vwith lrubber disk 23 to vinsure an air-tight j oint." YThe holder is se-A 'c'ured'to the lower end of ahollowro'd24,

onveys -'havingja handle 25 at the upperendarranged inthe same vertical plaerasthe holder. The

rod passes'through an opening in theftop of the Vgenerator and is provided with a swiveled supporting-bar 26, ,which` when the carbidholder is in operative position' restsfupon the top of the partition and supportsthe holder. The top of' the carbid i holder is locked in closed position by a spring-pressedfbolt 2,7, A shbrt chain chain-3l is connectedY at one end tochain-29,

Y passed around theV holder over rollers 32 and up through the hollow rod 24, a ring 33` be- '.ing secured to its upper end and adapted for engagement withfa hook '3i on therod for a purpose hereinafter described. An inletopening 35, having a gas-tight cover V36, is provided'in the top of the generatorf'above the chargingchamber.2,it being ofsu'ch size and so positioned as `to permit .the ready cleansing and fillingl ofv the carbidholder when the latter has been drawn in the proper position.

Assuming the carbid-holder to have been drawn up to the inlet-opening, carbid is placed in the holder, its top is closed, preventing the entrance of water, and the holder lowered beneath the surface of the water and turned beneath the partition and raised into the generating-chamber 3, the bar 2G being turned over the upper edge of partition 4 to support the holder. This manipulation of the holder is readily accomplished through operation of rod 24 by means ot` handle 25, which handle indicates at all times the position ot' the holder with relation to the rod 24. Vhen it is desired to generate gas, the chain 3l is drawn upward by means of ring 33 and the latter placed over hook 34. This movement of chain 3l will, through chain 29, withdraw the bolt 27 from its keeper and raise the top 22 of the holder, admitting water to the carbid in the holder to generate gas. The connections between chains 29 and 3l is such that a slight movement of chain 3l will withdraw the bolt, while a further movement will cause the power to be exerted against stud 30, relieving' the bolt of the lifting strain of the chain;

From the above description it will be seen that we have provided a generator in which the carbid, while entirely surrounded by water, is not affected thereby except atvthe will of the operator and also wherein the exhausted material may be conveniently and quickly removed and a fresh charge readily placed in the holder.

Our invention contemplates a plurality of carbid-holders conta-ined in the same or separate generators, as several such holders may be charged and placed in position and the carbid remain neutral until gas is needed, or one holder may be withdrawn from operative position and charged while another holder is in use producing gas, and this may be readily accomplished in the same generator, as the water in the charging-chamber will prevent leakage of the gas generated.

Referring to Fig. 4, wherein is shown the means for sounding an alarm when the quantity or" gas in the gasorneter is reduced beyond a serviceable limit, 37 denotes a strip of insulating material projecting from the gasometer-tank 14 and carrying two bindingposts 38,which are electrically connected with a battery 39 and abell 40, as shown, the wire leading from the battery to one post and from the second post to the bell, the other Wire of the circuit leading directly from the battery to the bell. 4l represents a strip projecting laterally from the gasometer-bell 13. From the free end of this strip depends a coil-spring 42, carrying at its lower end a metal strip 4S of suiticient Width to contact With both binding-posts 38. In the reduction ofgas the bell will descend until the strip 43 contacts with the binding-posts 38, when the circuit will be completed and the bell will be sounded. By the use of spring 4l the further descent of the gasometer-bell is not interfered with after the alarm is initially sounded, and the alarm will continue ringing until suflicient gas has entered the gasometer and operated the gasometer-bell to separate the strip 43 and the binding-posts. In order to cause a regular descent of the bell after contact of the strip 43 with the binding-posts, We prefer to duplicate this device, without the electrical features, on the diametrically opposite side of gasometer.

Having thus described our invention, what we claim as new, and desire to secure byLetters Patent, is-

l. In an acetylene-gas apparatus, a generatot` adapted to contain water, said generator comprising a charging-chamber and a generating chamber, a carbid holder having a hinged lid normally locked to prevent the admission of Water to the holder, a hollow rod connected with the holder and projecting through the top of the generator, said rod serving to move the holder into the chargingchamber for charging and into operative position in the generating-chamber, and lneans operative through said rod for unlocking and raising the lid of the holder.
